Investor sentiment and share returns: evidence on family firms

Abstract

Purpose The purpose of this paper is to examine the effect of investor sentiment on share returns, exploring whether this effect is different for public family and non-family firms. Design/methodology/approach The author uses the European Economic Sentiment Indicator data, from Directorate General for Economic and Financial Affairs as a proxy for investor sentiment and focused on the share returns of family and non-family firms, using panel data methodology. Findings Using data from listed family and non-family firms for the period between 1999 and 2011, in accordance with behavioural finance theory, the results indicate that there is a negative relationship between sentiment and share returns. In addition, the author found no difference between family and non-family firms in what concerns the effect of sentiment on share returns. The evidence also suggests that young, large and medium growth firms are most affected by sentiment. Finally, the results suggest that the evidence concerning the relationship between sentiment and returns is sensitive to the proxy used to measure the sentiment. Research limitations/implications A limitation of this study is the small size of the sample, which is due to the small size of the Portuguese stock market, the Euronext Lisbon. Originality/value This paper offers some insights into the effect of investor sentiment on the share returns in the context of public family firms, a strand of finance that is scarcely developed. It also contributes to the analysis of a small European country, with a high concentration of equity ownership.
